Turning Options Flags On or Off
There are two types of flags in the 2i software. The first
type is used to toggle an action (ON or OFF) or
change the status of an option (enable/disable) while
the second type is used to set the status of a flag from
a list of possible choices.
The first type is a square box (also called check box)
and is used to toggle an action ON or OFF. Changing
the state is accomplished by selecting the square and
pressing the Enter button. Depending on the context,
the check box status might not be saved in memory
and exiting the screen will reset it to its normal
operating state. A checked square indicates a
selection (or ON state,) while the empty square
shows the option deselected (or OFF state,).
The second type of flag is a circle (also called radio
button) and is used to enable () or disable () a flag
and the resulting choice is stored in memory. When
this option is present, only one of the radio buttons
within the group can be selected by pressing the Enter
button. It is used when multiple choices are available
but only one choice can be made.
Using the Alphanumerical Keypad
Prior to starting a test in summary or monitoring
reporting mode, the operator can enter a filter/location
ID using the integrated alphanumeric keypad. The
operator must press the keypad function key to bring
up the keypad on the screen.
Navigate to a character using the arrow keys and
press Enter to select it. To toggle between the alpha
and numerical keypads, select the “1 2 3” or the “A B
C” selection and press Enter.
When the operator has finished entering his selection,
he may select the enter key “” or the “Exit” key.
